This invention relates to tools for tightentightening the wires in some cases without ing wires and particularly wires for holding the other parts of the assembled tool, covers on containers. Figure '1' 1 represents a fragment of a ham- In the use of various forms of containers per, with one of the cover bail wires threaded and especially hampers it has been found ad-' through a fulcrum eye on the side of the visable to utilize wire loops adapted to be hamper, and the end of such-wire held in tightened over the covers of such containers. the slot, for twisting the wire around the Such wires cannot be satisfactorily tightmandrel to tighten the bails. ened manually as they tend to cut into the Likenumerals on the diiferent figures rephands of the operator when sufficient force resentl'like'parts.

As the rod Figure 6 shows a detail View of the windis then rotated, the body of the wire is ing mandre lor rod which may be utilized for twisted around the rod till the Wireor wire 9 bails are sufliciently tightened, as indicated in Figures 4, 5 and 7. I

When the rod is used in the assembled tool, the operator after such tightening tilts the tool in the direction indicated by the arrows, and the body or bend of the wire will be held from slipping backby its sharp bend over the fulcr-ums, as the fixed eyelet 21 in Figure 4, or over the bail wire in Figure 5. The rod is then slipped from wire coils and the coils cut away and the free end of the tightened wire then manually twisted beneath its body as indicated by dotted lines 22 in Figure 4, and so locked.

The most important features of the winding red are the holding jaws and a tapered slope of the part of the rod whereon the wire is Wound. The slope permits the rod to be easily withdrawn from the coils when the wire has been tightened. This tapered form is best shown in Figure 6, whereon the rod is-seen to decrease in diameter from the point indicated at 23, gradually down to the ends of the jaws 20. Without this slope the coils when wound around the rod, would bind,

and prevent the quick or easy separation thereof.

When used in the assembled form the rod may be provided with a ratchet wheel 24, and pawl25, to prevent the rod turning backward. This assembled construction is particularly important when required for heavy duty.

For light work the rrod may :be generally used for tightening without the frame. As shown in Figure 7. There the rod is positioned adjoining the fulcrum eye 21', and the wire end 11 inserted between the aws, and then as the rod is turned'the body of the wire when so drawn through the eye is maintained on an open curve by the rod, and so slides through the eye more freely than it would if guided directly back over the top of said eye. lVhen sufficiently tightened this wire may be bent abruptly back over the eye, andv the rod withdrawn, and the free end of the wire looked as described.

Having described my invention I claim as new for Letters Patent: 1

1. A tool for tightening wire fasteners over container covers, comprising a holding frame, an angular abutment plate on the lower end of the frame for holding the tool in suitable position against the top and side of the container, a winding rod rotatably mounted through the frame with means for turning the rod at one end thereof, and the other end provided with oppositely positioned jaws adapted for holding a wire to be twisted upon the rod, the jaw end of the rod tapered and increasingin diameter from the end of the jaws for a distanceover which the wire may be wound, said taper to facilitate the separation of the rod from the wire coils when the wire has been tightened.

2. A tool for tightening wire fasteners over container covers, comprising a holding frame, an abutment block on one end of the frame, provided with a notch for holding a wire while being tightened, adjustable lugs extending from the block to hold the same in position when a wire is tightened, a mandrel provided with a slot in one end for holding a portion of the wire, to be twisted around the mandrel, the outside of the mandrel tapered back from the jaw end to facilitate separa .tion thereof from the wire, the mandrel rotatably mounted in the frame with means for .turning'the same.

In testimony whereof I aflix my signature.
